Bevinsee 16PCS Valve Cover Bolt Kit
The Bevinsee kit is CAD-designed from 6061-T6 billet aluminum and finished with a hard anodize for long-lasting corrosion resistance. It includes valve cover bolts and Vitton seals for reliable oil containment. This kit is best for builders seeking a premium, durable hardware set that aligns with Honda B-series aesthetics. Choose this if you want a sturdy, visually appealing upgrade for B16/B18 engines with VTEC compatibility. Caution: may exceed standard torque on some factory covers; verify torque specs before installation.
DEWHEL B-Series Low-Profile Hardware
The DEWHEL kit targets B-Series engines with a low-profile valve cover design. It’s compatible with B16A2/A3, B17A1, B18C1, and B18C5 variants, making it a strong choice for engines using slimmer valve covers where clearance is tight. Best for builds prioritizing compact hardware without sacrificing strength. If your setup requires a thicker head, this kit may be less ideal; confirm clearance with your cover before purchasing.
GoaMotors Valve Cover Gasket Set
The GoaMotors gasket set focuses on broader gasket compatibility for Honda/Acura B20B4 and B20Z2 family engines, matching several vehicle lines like 1990–1993 Integra 1.8L and 1994–2001 Integra 1.8L. Best for a full gasket replacement during a heads-up rebuild or head refresh. It provides multiple part-number matches, which is useful for matching exact OEM-style seals. Limitation: it’s a gasket set, not a pure hardware kit; use where you also need new gaskets, not just bolts.
REMTUNE Valve Cover Mount Bolt Kit
REMTUNE offers OEM-spec hardware in a 4-pack, designed for Honda/Acura Integra and Civic builds, with B16, B18, and H-series compatibility. Best for those performing a straightforward bolt replacement with easy installation. It’s noted for easy handling and a confidence-inspiring fit. Limitations: not a complete gasket set; ensure you already have or plan to purchase corresponding gaskets and washers if needed.
Street Sport Industries Valve Stem Seals Set
This 16-piece valve stem seals set targets Honda/Acura B18A/B18B/B20/B21/H23 engines. Best for comprehensive stem seal refreshes, especially during head work or rebuilds. It addresses common oil seepage and smoking symptoms by improving valve stem sealing. Limitation: designed for seals, not all bolts or gaskets are included, so plan to source additional hardware if required.
SpeedFactory Titanium Valve Cover Hardware Kit
SpeedFactory’s titanium kit is aimed at performance builds for B-Series NON-VTEC engines. It uses titanium washers with Viton grommets and comes in raw or burnt finishes. Best for those seeking reduced weight and a show-ready appearance with high corrosion resistance. Caution: titanium hardware may require torque adjustments to avoid over-tightening and potential galling on aluminum threads; follow factory torque specs.
BBC Valve Cover Bolt & Spreader Tab Kit
This kit provides 14 spreader tabs with premium 304 stainless steel bolts and tabs designed for Big Block Chevy valve covers. Best for ensuring even pressure distribution to prevent leaks on stamped steel valve covers. While not a direct match for Honda B20, it demonstrates how spreader tabs can help seal reliability in engine builds that use similar gasket concepts. Limitation: not designed for B-series Hondas; ensure correct pattern fitment before use in a non-native engine setup.
Buying Guide
What should you consider when choosing B20 valve cover hardware?
- Engine compatibility: Verify the kit matches B20, B18, or related B-Series blocks and whether VTEC compatibility matters for your build.
- Material and finish: Aluminum and titanium offer strength and reduced weight. Stainless steel adds rust resistance for show or street use.
- Seals and gaskets: Some kits include seals or gaskets; others are pure hardware. Decide if you need a full gasket set in the same purchase.
- Profile and clearance: Low-profile washers or slim hardware may be necessary for tight engine bays or specific valve cover designs.
- Torque guidance: Some premium kits require following factory torque specs to avoid over-tightening or under-tightening.
- Aesthetics vs. practicality: Titanium and polished stainless offer looks for show cars, but may cost more and require careful handling during installation.
Frequently Asked Questions
- What is valve cover hardware used for?
Valve cover hardware secures the valve cover to the cylinder head, seals the oil, and maintains proper pressure and alignment of the cover and gasket.
- Do I need a gasket set with valve cover bolts?
Not always. Some kits pair hardware with gaskets or seals, while others are just bolts and washers. Match to your current setup and rebuild plans.
- Can I reuse old valve cover hardware?
Reusing hardware can risk threads stripping or uneven sealing. Use new hardware when rebuilding or resealing a cover.
- Which material is best for durability?
6061-T6 aluminum hardware is durable and lightweight; stainless steel resists corrosion; titanium offers weight reduction but may be pricier and require careful torque control.
- Is it okay to mix hardware from different brands?
Mixing hardware is not recommended unless you confirm compatibility with thread size, length, and torque specifications for your engine model.
